Ganivsor 405143 Mower Deck Belt 1/2" x 105.75" Fits 46-Inch Deck Compatible with Husqvarna YTH22V46 Craftsman T2000 T3000 Poulan Pro Lawn Tractor High-Strength Reinforced Fiber for Long-Lasting

What It Is

This is a 1/2-inch wide, 105.75-inch long mower deck belt designed for 46-inch cutting decks. It drives the blades on Husqvarna YTH22V46, Craftsman T2000/T3000, and Poulan Pro lawn tractors. It’s a replacement part for worn or broken OEM belts.

Fitment & Compatibility

• Measure your old belt first – The exact length is 105.75 inches (1/2 inch wide). If your belt is stretched or broken, measure the deck’s belt path or compare to the original part number.
• Deck size – Only fits 46-inch decks. Do not use on 42-inch or 54-inch decks.
• Model compatibility – Works with Husqvarna YTH22V46, Craftsman T2000/T3000, and Poulan Pro tractors with a 46-inch fabricated or stamped deck. Check your mower’s model number (e.g., 917.XXXXX for Craftsman) to confirm.
• OEM cross-reference – Replaces Husqvarna 532405143, 532 40 51-43, and Craftsman 405143. It’s an aftermarket belt, not OEM, but matches these part numbers.
• What to verify – Ensure your deck has a single belt system (not dual belts) and that the belt routing matches the original (usually around two idler pulleys and three spindles).

Key Things to Know

• Reinforced fiber construction – The belt uses high-strength fibers for durability, but it’s not Kevlar. Expect similar lifespan to OEM belts (2-3 seasons with normal use).
• Installation difficulty – Moderate. Requires removing the deck or using a belt tensioner tool. Belt routing diagrams are available online for your specific model.
• Common gotcha – The 105.75-inch length is critical. A belt that’s even 1/4 inch shorter or longer can cause slippage, poor blade engagement, or premature wear. Measure twice.
• No pulley included – This is just the belt. Inspect your idler pulleys and spindles for wear before installing; a worn pulley will destroy a new belt quickly.

Should You Buy It

If you have a 46-inch deck Husqvarna, Craftsman, or Poulan Pro tractor and need a budget-friendly direct replacement for the OEM 405143 belt, this is a solid pick. It’s not a heavy-duty upgrade, but it’s correct for standard residential use and priced well below dealer parts. Skip it if you’re looking for a premium extended-life belt or if your deck uses a different length.
